Wheeling herself around Doha's Thumama complex for medical evacuees from Gaza, Maryam Ahmed wears a look of determination, breaking into a smile when she sees someone she knows.

The six-year-old was evacuated to Qatar from Gaza in February after her home was hit by an Israeli strike which killed her mother, father and brother, and took her right leg.

Sitting in her new wheelchair, Maryam hitches up the skirt of her colourful, floral patterned dress to reveal what remains of her limb, amputated above the knee.

Lebanon's Hezbollah said six of its fighters were killed in Israeli strikes on Tuesday, with the group claiming cross-border attacks and low-flying Israeli warplanes breaking the sound barrier over Beirut.

Hezbollah has traded near-daily fire with Israel in support of its ally Hamas since the Palestinian militant group's October 7 attack on Israel triggered war in Gaza.

Palestinian officials said Israeli forces killed 12 people in three separate raids in the northern West Bank on Tuesday, as violence in the occupied territory showed no sign of abating.

Five people were killed in the Jenin area and four in Aqaba town in Tubas district when Israeli forces carried out early-morning raids, the health ministry in Ramallah said.

The Israeli army said three people were killed and two arrested in another raid in the village of Kafr Qud, west of Jenin.

Saudi oil giant Aramco on Tuesday reported net profit of $29.07 billion in the second quarter, a slight drop from the same period last year as output remained subdued.

The decrease of 3.4 percent "mainly reflects the impact of lower crude oil volumes sold and weakening refining margins", the company said in a statement posted to the Saudi stock exchange.

Saudi Arabia, the world's biggest crude exporter, is currently producing roughly nine million barrels per day (bpd), well below its capacity of 12 million bpd.

After seeing his once-lush rice field shrink in recent years due to relentless drought, Iraqi farmer Muntazer al-Joufi fought back using tougher seeds and water-saving irrigation techniques.

"It's the first time we're using modern techniques that consume less water" to cultivate rice, Joufi, 40, said as he surveyed his land in the central province of Najaf.

"There is a huge difference" compared to flooding the field, Joufi added, referring to a traditional method by which the land must stay submerged all summer.

China's embassy in Beirut urged citizens to "travel with caution" should they visit Lebanon, warning they face "higher security risks" as fears of a regional conflict soar.

In a statement issued Monday evening Beijing time, the embassy warned citizens the situation in the country was "grave and complex".

"The Ministry of Foreign Affairs and the Chinese Embassy in Lebanon remind Chinese citizens to closely monitor the evolution of the local situation and to travel with caution in Lebanon in the near future," the embassy said on its official WeChat account.

A rocket attack on a base in Iraq wounded seven Americans, a US official said on Tuesday, with Washington blaming an Iran-backed militia group and saying such violence will not be tolerated.

The rocket fire the previous day was the latest in a series of attacks targeting Ain al-Assad base in recent weeks, which hosts American troops as well as other personnel from the US-led coalition against the Islamic State jihadist group.

It came at a time of already heightened tensions in the Middle East, with the region awaiting an expected counterattack by Iran on Israel.

A key Tunisian opposition figure and potential candidate for the upcoming presidential election jailed since October was sentenced to two years in prison late Monday night, according to local media.

Abir Moussi, 49, head of the Free Destourian Party and a former parliament member, had submitted her candidacy on Saturday via her lawyers, two days before her sentence, which local radio Mosaique FM reported.

Moussi is a staunch critic of the incumbent Tunisian President Kais Saied and has been sentenced under Decree 54, a law enacted by Saied in 2022 to combat "false news".

As Israeli Prime Minister Benjamin Netanyahu repeats his promises to bring the Gaza hostages home, he is facing a growing chorus of sceptics who worry he's not interested in a deal with Hamas.

Rocketing regional tensions are increasing the desperation of families and friends of the remaining 111 captives, including 39 known to be dead, taken during the bloody October 7 attack that sparked the Israel-Hamas war.

"We're actually very concerned and worried that there is no time," Gil Dickman, whose cousin Carmel Gat is among the captives, told AFP.

The United Nations said Monday that nine employees of its agency for Palestinian refugees (UNRWA) "may have been involved" in the October 7 attack on southern Israel by Hamas, which sparked war in Gaza, and have been fired.

"We have sufficient information in order to take the actions that we're taking -- which is to say, the termination of these nine individuals," UN spokesman Farhan Haq said.

Haq said the organization will need to evaluate any further steps to "fully corroborate" the allegations.
